Hypothesis Following weight loss surgery, many patients initially experience nonspecific foregut symptoms. Helicobacter pylori infection of the gastric remnant may be associated with foregut symptoms.
Design Inception cohort.
Setting University hospital.
Patients Ninety-nine consecutive patients being evaluated for weight loss surgery.
Intervention All patients underwent preoperative esophagogastroduodenoscopy and H pylori testing.
Main Outcome Measures Foregut symptoms were documented at routine post–weight loss surgery follow-up visits.
Results Preoperatively, 24% of patients tested positive for H pylori. Postoperative foregut symptoms were significant in 48% of the H pylori–positive group, and 19% of the H pylori–negative group (P = .02). This increase remained even after controlling for age, sex, preoperative presence of antritis, type of surgery performed, and body mass index (odds ratio, 3.6; 95% confidence interval,1.1-11.8). Patients with prolonged symptoms who tested positive for H pylori were given an eradication treatment.
Conclusions The prevalence of H pylori infection in patients undergoing weight loss surgery is high, and a significant proportion of them have postoperative foregut symptoms. Consideration should be given to H pylori treatment in these patients.
